Abstract
Global reanalysis has become well established, providing comprehensive and good quality records of past weather. Modern NWP (Numerical Weather Prediction) systems are run with historical observations to provide consistent and coherent analyses of weather over decades. These have found much use in climate research and elsewhere.
Global reanalyses are expensive to run. There is a trade-off between horizontal model resolution and running cost which means that these typically don’t match the resolution of operational NWP. Regional reanalyses are able to run at higher resolution by restricting themselves to small regions of the globe. Regional reanalyses depend on global reanalyses to define the large-scale weather. They then attempt to add detail. High resolution observations and modelling help resolve more local weather and extremes. The meeting will look at examples of this from across the globe. It will consider the benefits and uses of regional reanalysis, and also the disadvantages compared to global. Overall, what can regional reanalysis provide?
